Python - 字典嵌套在列表中，列表嵌套在字典中

Question

当我执行 requests.get 时，我会收到如下所示的响应，数据来自 LoL API:

{
"champions": [
    {
        "id": 111,
        "stats": {
            "maxChampionsKilled": 2,
            "maxNumDeaths": 5,
            "mostChampionKillsPerSession": 2,
            "mostSpellsCast": 0,
            "totalAssists": 25,
            "totalChampionKills": 2,
            "totalDamageDealt": 40838,
            "totalDamageTaken": 27900,
            "totalDeathsPerSession": 5,
            "totalDoubleKills": 0,
            "totalFirstBlood": 0,
            "totalGoldEarned": 11070,
            "totalMagicDamageDealt": 21083,
            "totalMinionKills": 56,
            "totalPentaKills": 0,
            "totalPhysicalDamageDealt": 12876,
            "totalQuadraKills": 0,
            "totalSessionsLost": 1,
            "totalSessionsPlayed": 1,
            "totalSessionsWon": 0,
            "totalTripleKills": 0,
            "totalTurretsKilled": 1,
            "totalUnrealKills": 0
        }
    },

我正在努力获取“统计数据”中的数据。我真正想做的是类似于以下内容:

champ_data = received['champions']['stats']['totalSessionsPlayed']
print(champ_data)

但是它不起作用，因为“champions”后面有一个“[”，我收到错误:

TypeError: list indices must be integers, not str

Answer 1

你想要这个

received['champions'][0]['stats']

查看第一个冠军的统计数据。或者，这个

received['champions'][n]['stats']

nth 冠军的统计数据。或者，这个

[champion['stats'] for champion in received['champions']]

查看每个冠军的统计数据列表。
